Risk of electrical shock
Always disconnect the fixture
from AC power before and while
servicing.
Removal of any cover exposes connectors
that carry lethal electric currents. While
working on a fixture under power:
• Make sure the fixture is electrically
grounded.
• Use a supply with ground-fault-inter-
rupt protection.
• Never touch any connector that carries
voltage.
• Be careful with tools that conduct elec-
tricity.
Risk of UV radiation and
lamp explosion
Discharge lamps emit harmful ultraviolet
(UV) light that can cause eye and skin burns
through direct exposure. They also work
under high pressure that occasionally causes

them to explode. To eliminate the risk of
injury from the discharge lamp,
• Never operate the lamp with covers or
lenses removed.
• Do not look directly into the light.
Electrostatic discharge
Printed circuit boards (PCBs), individual
ICs, and Hall sensors can be damaged by
electrostatic discharge (ESD). To avoid
damaging these ESD sensitive parts:
• Ensure that you and your tools have the
same potential (ground) as the fixture
before and when handling any of the
above components.
• Store PCBs in antistatic (electrically
conducting) bags and store ICs in anti-
static foam.
• Power off the fixture and allow capaci-
tors do discharge before removing or
inserting components on the PCB.
Inductive loads
Power off the MAC 2000 Wash before
connecting or disconnecting step motors.
Failure to do so can damage the motor
drivers.
Threadlock
Threadlock is highly recommended on all
m a c h in e s c re w s e x ce p t s el f- ta p p i n g
(Taptite) screws to prevent loosening.
Threadlock should be reapplied if the
screws are removed.
Two types of threadlock are available from
Martin. For set screws, use Loctite 290, P/N
37020002. For all other screws, use Loctite
243, P/N 37021002. Both come in 10 ml
tubes.
Be careful to avoid getting any material on
shafts or axles. A needle and syringe makes
an idea application tool.
Long set screws: Start the screw and turn it
until it contacts the shaft. Back the screw 2
turns, apply a small drop or 2 of Loctite 290
to the threads, and then tighten the screw as
you normally would.
Short set screws: Back the set screw out of
the adaptor until 2 threads stick out of the
shaft. Apply a small drop or 2 of Loctite 290
to the threads, and then tighten the screw
within 60 minutes.
Other metric screws: Apply a drop of
Loctite 243 (blue) to 3 or 4 threads, or
spread a thin stripe with a syringe, before
starting the screw.
Self-tapping screws
The reuse of self-tapping "Taptite" screws
is not recommended as these screws are
designed to cut threads and can strip
existing threads when reinserted. Change to
metric hardware of the same size when
reinstalling parts originally held with
Taptites.
If installing a new part without threads, use
new self-tapping screws. Do not use old
taptites to cut new threads!
Lubrication
Silicone grease, P/N 37302002, "Silicon
grease, clear, 100g", is used, for example, to
lubricate brass bushings inside of pulleys
and between moving metal plates such as
the motor bracket for color wheel 1 on the
MAC 2000 Wash.
Slides are generally lubricated with the high
viscosity silicone oil, P/N 37302005, "High
viscosity silicone oil, 200 ml, in applicator
bottle."
Bearings are lubricated with P/N 37302004,
"Silicone oil, 200 ml, in applicator bottle".
